Claro, vamos a evaluar la función [tex]\( f(x) = 2x - 6 \)[/tex] en los puntos [tex]\( x = -7 \)[/tex] y [tex]\( x = 0,5 \)[/tex].

Paso 1: Evaluar la función [tex]\( f(x) \)[/tex] en [tex]\( x = -7 \)[/tex].

[tex]\[ f(-7) = 2(-7) - 6 \][/tex]

Primero, multiplicamos [tex]\( 2 \)[/tex] por [tex]\( -7 \)[/tex]:

[tex]\[ 2 \times -7 = -14 \][/tex]

Luego, restamos 6:

[tex]\[ -14 - 6 = -20 \][/tex]

Por lo tanto, [tex]\( f(-7) = -20 \)[/tex].

Paso 2: Evaluar la función [tex]\( f(x) \)[/tex] en [tex]\( x = 0,5 \)[/tex].

[tex]\[ f(0,5) = 2(0,5) - 6 \][/tex]

Primero, multiplicamos [tex]\( 2 \)[/tex] por [tex]\( 0,5 \)[/tex]:

[tex]\[ 2 \times 0,5 = 1 \][/tex]

Luego, restamos 6:

[tex]\[ 1 - 6 = -5 \][/tex]

Por lo tanto, [tex]\( f(0,5) = -5 \)[/tex].

En resumen, la función evaluada en los puntos dados es:

[tex]\[ f(-7) = -20 \][/tex]
[tex]\[ f(0.5) = -5 \][/tex]
